摘要
采用低功率脉冲加热预处理雾化铜粉 ,选择合适的仪器条件处理单个氧峰的方式 ,应用红外吸收法测定雾化铜粉中氧 ,方法简单、快速、准确。氧的回收率为 96 1%～ 99 6% ,相对标准偏差 (RSD)小于 1 3 5 %。
It was identified that the removal of the organic film on the surface of copper powder was absolutely necessary for the determination of oxygen,and the pulse heating method with low power was adopted for this pretreatment.The appropriate instrument conditions for handling each oxygen peak were selected.This method is simple,rapid,accurate and precise.The recoveries for oxygen were in the range of 96.1%～99.6%,RSD was less than 1.35%.
